N-M1200C - Miller N-M1200C AccuLock MDX Nozzle, 1/2" Flush, Copper (2-Pack)

Optimize Your MDX-250 Performance

Experience the next evolution in MIG welding consumables with the Miller AccuLock MDX N-M1200C Nozzle. Designed specifically for the MDX-250 and MDX-250 EZ-Select MIG guns, this nozzle is a critical component of the AccuLock system, which addresses the most common frustrations welders face: wire feeding issues and loose consumables. By integrating seamlessly with the AccuLock diffuser and contact tips, this nozzle helps create a flawless wire-feed path from the feeder all the way to the arc.

Stays Tight, Every Time

One of the standout features of the N-M1200C is its thread-on design. Unlike slip-on nozzles that can become loose and wobbly as the gun heats up, the AccuLock nozzle utilizes coarse threads and a specialized steel retaining ring on the diffuser. This combination ensures the nozzle stays firmly in place during use and cleaning, maintaining consistent gas coverage and electrical stick-out. You spend less time adjusting your gun and more time welding.

Flawless Wire Feeding

The AccuLock MDX system is engineered to center and lock the liner into position at the front of the gun. When you install this nozzle, you are completing a system that aligns the contact tip perfectly with the liner. This concentricity significantly reduces drag and friction on the welding wire, leading to a smoother, more stable arc and fewer burn-backs. Whether you are a hobbyist in the garage or a professional in a fabrication shop, the reliability of the AccuLock system translates to cleaner welds and less downtime.

Durable Copper Construction

Built to withstand the rigors of welding, this nozzle is crafted from high-grade copper. Copper provides excellent thermal conductivity, pulling heat away from the front end of the gun to extend the life of your consumables. The 1/2-inch orifice and flush tip geometry make it an excellent all-around choice for various welding positions and joint configurations, offering a balance of gas coverage and joint accessibility.
